It plays and works the same in Mp or Sp section.
Theres no need for 2 missions ,SP/MP for all these Air War missions.
Is there any reason why ppl dont like or want to load it in the MP section?
I am interested to know cos i havnt played much SP since OPF and almost never play SP
now in arma 2.
If ppl really want to play it in SP all they have to do is change the desired pilot you wish to play in the editor to "Player" from "Playable" and then its a SP mission.
